Patent CA-2168268-C (CA)
Inventor: HOLMS RUPERT DONALD
IPC: A61K38/16
Filed: 1995-06-02
Granted: 2007-01-09
Abstract: L'invention concerne la production de préparations s'appliquant au traitement ou à la prophylaxie du SIDA et du lupus érythémateux aigu disséminé et des affections apparentées. L'invention est basée sur la découverte du processus déclenché dans le système immun par le VIH qui est à l'origine du SIDA. Le VIH possède un mécanisme spécifique qui active le système immun pour lui permettre de se répliquer, et cette même activation immune entraîne un processus auto-immun qui est éventuellement à l'origine du SIDA. La préparation s'appliquant au traitement comprend de nouveaux peptides synthétisés dont les séquences d'acides aminés sont dérivées d'une protéine humaine nommée ezrine et qui sont basés sur la séquence suivante: NH¿2?ThrGluLysLysArgArgGluThrValGluArgGluLysGluCOOH. Le mécanisme d'action de ces peptides fait qu'ils déclenchent des réponses immunes spécifiques, induites de manière rétrovirale, par une tolérance immunologique.

Abstract: A diffused light reflectance readhead is disclosed. The readhead employs an improved light emitting diode (LED) providing a more strongly collimated beam of light around a beam axis onto a reagent test pad. The reagent test pad is supported on a strip guide at an angle .alpha. of 5 degrees with respect to the perpendicular of the beam axis. It has been discovered that when .alpha. is between 3 and 8 degrees that specular reflection is dramatically reduced in relation to the small reduction in reflected light received by a sensor. The diffuse reflected light travels to the sensor by passing through a staircase optical baffle at an angle of 45 degrees to the perpendicular of the beam axis. The sensor converts the optical signal into an electrical one for processing and analysis. One embodiment of the present invention can detect the presence of glucose in a blood sample.

Inventor: LEMPKA BARBARA MARY-ANN
IPC: C02F1/52
Filed: 1997-08-22
Granted: 2002-05-21
Abstract: The surprising ability of the polysilicate microgels commonly known as "activated silica" to adsorb and to release heavy metals selectively as a function of pH is used in a novel method for separating metals from dilute aqueous solution by means of selective precipitation with and recovery from an activated silica absorbent, selected changes to the pH.  The process is particularly intended for the economic purification of contaminated waste streams to recover valuable but toxic heavy metals from such effluents at a lower cost than hitherto possible, using an activated silica substrate which may be regenerated by alkali treatment.

Title: Oxygen concentrator with beds' duty cycle control and self-test
Inventor: HART RUSSELL FRANK
IPC: A62B7/14
Filed: 1998-04-16
Granted: 2002-02-12
Abstract: A method of controlling performance of an oxygen concentrator having a first molecular sieve bed which is operated over successive control periods according to a duty cycle for alternately pressurizing and flushing the first molecular sieve bed and a second molecular sieve bed which is operated over the successive control periodsaccording to a reciprocal of the duty cycle for alternately flushing and pressuring the second molecular sieve bed, the method comprising the steps of adjusting the duty cycle and the reciprocal duty cycle during every second one of the successive control periods to prolong the pressurizing relative to the flushing of the first molecular sieve bed and to prolong the flushing relative to the pressurizing of the second molecular sieve bed, thereby degrading performance of the oxygen concentrator for reducingconcentration of oxygen producing by the oxygen concentrator; and adjusting the duty cycle and the reciprocal duty cycle during remaining control periods to prolong the flushing relative to the pressurizing of the first molecular sieve bed and to prolong the pressurizing relative to the flushing of the second molecular sieve bed, such that water vapor is purged from the first and second molecular sieve beds after pressurizing thereof. A further aspect of the present invention is the provision of a pressure-swing adsorption (PSA) subsystem performance check. This test is performed as part of a maintenance BIT (Built-In-Test) function. After verifying that the oxygen sensoraccuracy is acceptable using prior art techniques, a set of bleed valves are opened to load the oxygen concentrator at a specific flow. The oxygen concentration is then checked via the sensor to determine whether the PSA subsystem is operating to within specification (i.e. concentration limit above a predetermined level - such as 50%).

Granted: 2003-04-22
Abstract: Procédé, dispositif et article servant à corriger les erreurs de fréquences de porteuse. Un signal de modulation de fréquence est reçu par une antenne et transmis à un récepteur. Ce récepteur admet le signal de modulation de fréquence à la fréquence de porteuse et émet un signal de bande de base. Ce signal de bande de base est ensuite traité par un processeur de signaux numériques effectuant la correction et le décodage de la fréquence de porteuse afin de produire un flux de données qu'un microprocesseur transmet à un ordinateur central. Les différences entre la fréquence de porteuse de modulation de fréquence et la fréquence utilisée pour démoduler le signal de modulation de fréquence peuvent déplacer le niveau de polarisation de courant continu du signal de bande de base. Le processeur de signaux numériques corrige cette différence de fréquence au moyen d'une valeur de correction de réception appliquée ensuite à chaque échantillon de signal reçu. La transmission des données s'effectue depuis l'ordinateur central vers le processeur de signaux numériques par l'intermédiaire d'un microprocesseur. Le processeur de signaux numériques effectue le codage et la correction de fréquence de porteuse des données afin de fournir un signal de bande de base à un émetteur qui module ce signal de bande de base afin de produire un signal de modulation de fréquence à une fréquence de porteuse souhaitée. Les différences de fréquence entre la fréquence souhaitée de modulation de fréquence et la fréquence utilisée afin de moduler le signal de bande de base peuvent produire des erreurs dans les systèmes récepteurs. Le processeur de signaux numériques corrige cette différence de fréquence au moyen d'une valeur de correction d'émission qu'il applique ensuite à chaque échantillon de signal codé.

Abstract: An assembly for producing a finished shape for a rod after the last rolling stage of a multi stand steel mill. This apparatus provides an operation for correcting minor surface irregularities and shape distortion of the rod as it exits from the finishing roll stand. The apparatus consists of four rollers mounted in an assembly which resembles a roller entry guide except that the rollers are capable of producing changes in shape of a work product passing therethrough. The orientation of the roller axis is slowly and constantly changed to prevent wear distortion of the rollers which may result when the rollers are required to roll a malformed product from fixed roller axes. The rollers may be driven in some circumstances.
